Simon Pilgrim ea1b6ee366 [X86][SSE] Improved i8/i16 to f64 uint2fp vector conversions 
Followup to D10433 and D10589 that fixes i8/i16 uint2fp vector conversions by zero extending to i32 and using the sint2fp path (unless the target does actually support uint2fp).

Simon Pilgrim c36cfe7af0 [X86] Added 32-bit builds to fp<->int tests. 
Ensure that i686 x87/SSE/SSE2 targets all build.

Simon Pilgrim b504263e4a [X86][SSE] Sign extension for target vector sizes less than 128 bits (pt2) 
Add support for v2i8/v2i16 to v2f64 by using a sign extension to v2i32 before conversion to v2f64.

Simon Pilgrim 3aa039a4a8 [X86][SSE] Improved support for vector i16 to float conversions. 
Added explicit sign extension for v4i16/v8i16 to v4i32/v8i32 before conversion to floats. Matches existing support for v4i8/v8i8.

Simon Pilgrim cae7b94cbd [X86][SSE] Vectorize v2i32 to v2f64 conversions 
This patch enables support for the conversion of v2i32 to v2f64 to use the CVTDQ2PD xmm instruction and stay on the SSE unit instead of scalarizing, sign extending to i64 and using CVTSI2SDQ scalar conversions.
